“…Therefore, the vast majority of toxicological studies have been focused either on aquatic or agriculture-relevant organisms. In the first group, studies have analyzed toxicity on diatoms [ 212 ], algae [ 213 ], clams [ 214 ], mussels [ 215 ], oysters [ 216 ], and zebrafish [ 217 ]. For instance, ceria NPs have been coated with polysaccharides (levan and pullulan) or a monosaccharide (glucose) and their toxicity was evaluated on three aquatic organisms: The bacterium Vibrio fischeri , the crustacean Daphnia magna , and zebrafish Danio rerio .…”
